Abstract:
A multi-zoned paddle screen apparatus (100) is disclosed for separating fiber from a liquid medium during, for example, a grain wet mill or dry grind process. The apparatus includes a housing (106) having first and second zones (108a, 108b) situated adjacent one another along a length (L) of the housing (106). First and second screen sections (102a, 102b) having a plurality of openings (104) may be situated lengthwise within the housing (106) corresponding with the first and second zones (108a, 108b), respectively. The first and second screen sections (102a, 102b) have a circular cross-section, and the second screen section (102b) has a larger diameter than the first screen section (102a). An elongated shaft (130) situated lengthwise within the screen sections (102a, 102b) includes first and second conveyors (128a, 128b), which correspond with the first and second zones (108a, 108b), respectively, having a plurality of paddles (132). Each conveyor (128a, 128b) is configured to move material in a direction along a length of the screen (102a, 102b). There may be more than two zones (108a, 108b).
Abstract:
A baffle (32) includes a body member having a first surface (34), a second opposed surface (36), and an outer peripheral edge (38). An aperture (40) may be formed through the body member so as to define an inner peripheral edge (42). The inner peripheral edge (42) is distorted so as to be non-planar. An apparatus (10) includes a first conduit (14) having a first end, a second end, and a first channel extending therebetween. At least one baffle (32) is disposed in the first channel and includes a body member having a first surface (34), a second opposed surface (36), and an outer peripheral edge (38). At least one aperture (40) may be formed through the body member to define an inner peripheral edge (42). The inner peripheral edge (42) is distorted so as to be non-planar. A second conduit (12) may be disposed inside the first conduit (14) and extend through the aperture (40) in the baffle (32). The apparatus may, for example, be configured as an ultraviolet light reactor, a heat exchanger, or a static mixer.

Abstract:
A liquid treatment apparatus (10) for processing a liquid includes an inlet nozzle (12) having an orifice (16) for directing a flow of liquid through the orifice (16) to define a fluid jet, and a concial diffuser (18) including a tip (20), a base portion (22), and a curved surface (26) therebetween. The conical diffuser (18) is generally aligned with the orifice (1 6) such that the fluid jet impacts upon the tip (20) of the conical diffuser (18). Moreover, the curvature of the curved surface (26) is selected to maintain a substantially constant Froude number of the liquid along the conical diffuser (18).
Abstract:
The present invention relates generally to corn dry-milling, and more specifically, to methods for producing a high protein corn meal from a whole stillage byproduct produced in a corn dry-milling process for making ethanol and a system therefore. In one embodiment, a method for producing a high protein corn meal from a whole stillage byproduct includes, in a corn dry-milling process for making ethanol, separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion. The thin stillage portion is separated into a protein portion and a water soluble solids portion. Next, the protein portion is dewatered then dried to define a high protein corn meal that includes at least 40 wt% protein on a dry basis.

Abstract:
An apparatus (40, 200) for filtering a material from a medium includes a first housing (44, 204) having a wall with a plurality of openings formed therein, a conveyor (46, 206) disposed in the housing (44, 204) for moving the material therealong, and a conduit line (48, 208) communicating with the interior of the housing (44, 204) for supplying the medium to the apparatus (40, 200). At least one of the first housing (44, 204) and the conveyor (46, 206) rotate relative to a central axis to direct the medium toward the wall so as to separate the material from the medium. A method for filtering a material from a medium includes supplying the medium to a first housing, spinning the medium within the housing, passing the medium through a wall of the housing to separate the material from the medium, moving the material along the housing, introducing a fluid into the material within the housing, and washing the material using the fluid.
Abstract:
This invention is directed to a centrifuge rotor, such as for use in a disc nozzle centrifuge, having a bowl including an improved positioning and orientation of discharge nozzles for facilitating tangential flow of fluid discharged therefrom relative to the rotor bowl.
Abstract:
A liquid treatment apparatus includes a supply chamber for receiving a fluid, a discharge chamber for discharging the fluid, and a cavitation generating chamber extending from the supply chamber to the discharge chamber. The cavitation generating chamber is operable to generate cavitation bubbles. A method of treating a liquid includes directing a fluid from a supply chamber into a cavitation generating chamber by constricting the fluid through an orifice, wherein the orifice has a cross dimension that is substantially less than a cross dimension of the supply chamber, such that the velocity of the fluid is reduced so that the jet axial velocity head at the chamber outlet is less than the difference between the static pressure within the discharge chamber and the vapor pressure of the fluid. The method also includes discharging the fluid into a discharge chamber via a chamber outlet.
